A deeply eroded channel created by the concentrated flow of water. A gully consists of a variety of conditions that make erosion possible, such as climate change, fire, storms, or human efforts in eliminating natural vegetation that protects the soil. The erosion of gully should not be associated with winter precipitation and instead be more thought of as highly exacerbated thunderstorms. Gullies are also known to be capable of wreaking havoc on arable land due to headward erosion which makes it spread rapidly when set in soft rocks.
